JM W I N VEN ERNST HINTERHOLZL DEVICE FOR THE AXIAL ADJUSTMENT F ROLLS, PARTICULARLY GROOVED ROLLS The present invention relates to a device for the axial adjustment of rolls, particularly grooved rolls, which are displaceably arranged with their inserts in the frame of a rolling stand.

The problem with continuous casting plants and in particu lar with multibar continuous castings plants is to arrange the rolling stands used for the further shaping of the castings subsequent to the casting process so as to save most space, in order to achieve the closest possible side by side and in tandem arrangement of the rolling stands. Another aim is to design said rolling stands as light and simple as possible. The rolling stands shall be quickly and easily exchangeable as well as interchangeable, if desired. As opposed to usual rolling trains, the adjustment of the rollsi.e. the adjustment of the sizing grooveis effected with these breakdown trains following a continuous casting plant not on the spot but preferably in a roll workshop. Only aligning or adjusting work shall be done once the complete rolling stand has been installed and is ready for operation. The axial adjustment of the rolls is of particular importance for a careful sizing groove adjustment.

It is therefore desirable to design for rolling stands of the aforementioned type a simple and space-saving device, preferably located within the roll standard, for the axial adjustment of the rolls.

According to the invention this problem is solved by providing that at least one roll together with its inserts is adjustable in axial direction of the roll by one or two guide members arranged in slots of the roll standards and displaceable perpendicular to the roll axis, said guide members having wedgelike slide surfaces which coact with corresponding slide surfaces on the shoulder of one of the inserts.

Preferably each guide member is designed like an inverse U" and moved by a hollow threaded spindle, said threaded spindle being forcelocked to the shoulder of the insert by a bolt and a fixing plate.

The device for axial adjustment may be symmetrically arranged within the slots of the roll standard on either side of an insert.

In order that the invention may be more fully understood it will now be described by way of example, shown in the accompanying drawings, in which FIG. I shows a partly sectional front view of a rolling stand,

FIG. 2 a vertical sectional view along the line II-Il of FIG.

FIG. 3 a horizontal sectional view along the line Ill-Ill of FIG. 2, and

FIG. 4 is a left-hand elevational view of the rolling stand shown in FIG. 1 and illustrates another embodiment of the invention.

FIG. 1 shows the arrangement of two grooved rolls ll, 2 together with their inserts 3, 4, 5, 6 in the standards 7, 8 of the rolling stand having a detachable cap connection 9 and a rigid cross connection 10. The roll standards 7, 8 have slots Ill, 12, wherein the inserts 3, 4 are guided without play and the inserts 5, and 6 with clearances designated by a and b in FIG. 3. A hollow threaded spindle 15 moves the insert of the roll 2 horizontally by means of a guide member 13 engaging with the shoulder 14 of the insert 5, without a vertical change of its position.

FIGS. 2 and 3 illustrate the function of the device in more detail. The threaded spindle 15 is engaged by a nut 16, which is inserted in the guide member 13. The threaded spindle 15 is forcelocked to a fixing plate 17 as well as to the shoulder M of the insert 5 by a bolt 26 and the nut 29. Numerals 27 and 28 designate bearing bushings of the threaded spindle ll5. Bolts l8, I9, 20, 21 connect the fixing plate 17 in such a way with the shoulder 14 that the fixing plate 17 is displaceable along the slots 22, 23, 24, 25 but not revolvable.

The guide member 13 designated like an inverse U" is guided in the recesses 30, 31 of the roll standard 7 and vertically displaceable therein. The guide member 13 has two parallel slide surfaces 32, 33 inclined at a small acute angle to the vertical plane through the roll standard 7. The shoulder 14 has corresponding slide surfaces. When the spindle 15, which has a square 3d at its upper end, is turned to the right in the direction of the arrow, the guide member 13 moves vertically upwardly along the recesses 31), 311, while the engagement of the slide surfaces 32, 33 on the guide member 13 and on the shoulder M causes a horizontal displacement of the insert 5 and of the roll 2 as well as of the insert 6, without any vertical displacement of roll 2. 0n turning the threaded spindle to the right the roll 2 can thus be displaced in axial direction by the dimension b, and on turning it to the. left by the dimension a; the aggregate dimension 1; and 1; amount in practice to several millimeters, sufficient for compensating for any inaccuracies due to assembly and manufacturing work.

The adjustment device is manually operated and is preferably installed on either side of the insert 5 and within the roll standard 7. The opposite insert 6 is guided in the roll standard it in slot 12 with the same play a plus b as the insert 5.
